User manual ROTEL RT-222

[. . . ] If the unit is exposed to moisture, or a foreign object gets into the enclosure, immediately disconnect the power cord from the wall. Take the unit to a qualified service person for inspection and necessary repairs. Read all the instructions before connecting or operating the component. Keep this manual so you can refer to these safety instructions. [. . . ] Some Surround EX titles do not have the detection "flag" encoded on Rotel XS 6. 1 and 7. 1 Channel Surround The RT-222 also features Rotel XS (eXtra Surround) processing provides extended surround performance on 6. 1 and 7. 1 channel systems. The key benefit of Rotel XS is that it works at all times with all multichannel digital signals, even those that might not otherwise activate Dolby Digital EX or DTS-ES surround decoding for the center back channel(s). Always available when center back speaker(s) are configured in the system setup, Rotel XS decodes the surround channels and distributes the extended surround channels to the center back speaker(s) in a way that tends to create a diffuse surround effect. Rotel XS works with matrix-encoded surround signals (such as nonflagged DTS-ES and Dolby Surround EX discs) as well as digital source material that is not Dolby Surround EX encoded (such as DTS 5. 1, Dolby Digital 5. 1, and even Dolby Pro Logic II decoded Dolby Digital 2. 0 recordings). DSP Music Modes Unlike all of the formats mentioned above, the RT-222 offers four surround modes that are not part of a specific recording/playback system. These modes (MUSIC 1­4) use digital signal processing that adds special acoustic effects to any signal. DSP processing can be used with Dolby Surround recordings, Dolby Digital recordings, CDs, radio broadcasts, or any other source material; however, typically DSP settings would be used with source material for which there is no specific surround decoder. Other Digital Formats Several other digital formats are not surround sound formats at all, but rather systems for digital 2-channel recordings. PCM 2-channel: This is an uncompressed 2-channel digital signal such as that used for standard CD recordings and some DVD recordings, particularly of older films. 27 English HDCD®: This system uses higher bit rates and a variety of enhancements to improve the sonic performance compared to standard audio CDs. These discs, labeled HDCD, can be played on standard CD players. However, when the digital signal is decoded using an HDCD decoder like that in the RT-222, they will provide exceptional musical reproduction. DTS Music 5. 1 Discs: These discs are a variation of audio CDs that include a DTS 5. 1 channel recording. The RT-222 decodes these discs just like a DTS movie soundtrack when played on a CD player or DVD player with a digital output connection. · Downmixed 2-channel playback of Dolby Digital 5. 1 or DTS recordings. · Dolby 3-channel stereo (left/right/center) of 2-channel recordings. · 5-channel or 7-channel stereo from 2-channel recordings. · One of four MUSIC modes for DSP concert hall simulation from 2-channel recordings. · Dolby Pro Logic II cinema or music mode matrix decoding of 2-channel recordings. · DTS Neo:6 cinema or music mode matrix decoding of 2-channel recordings. · Dolby Digital Surround EX decoding of Dolby Digital 5. 1 channel recordings or Dolby Digital Surround EX discs that do not trigger automatic decoding. A digital signal coming into the RT-222 will be recognized and properly decoded. However, on a DVD with multiple soundtracks, you must tell the DVD player which one to send to the RT-222. For example, you may need to use the DVD's menu system to select the Dolby Digital 5. 1 or DTS 5. 1 soundtrack rather than the default Dolby Digital 2. 0 Dolby Surround soundtrack. NOTE: Additionally, you can configure a default surround mode for each input using the INPUT SETUP menu (see the Setup section of this manual). Combined with the auto-detection of Dolby Digital 5. 1 and DTS, this default surround setting makes operation of the RT-222 surround modes totally automatic. For example, if you set Dolby Pro Logic II movie mode as RT-222 Surround Sound Receiver 28 DTS, DTS-ES Matrix 6. 1, DTS-ES Discrete 6. 1, DTS 96/24, Dolby Digital, MP3, MPEG Multichannel, HDCD (96kHz), and PCM 2-channel (96kHz) digital signals are auto-detected and cannot be overridden. [. . . ] The mechanical clicking of the relays is normal. · During switching, it may take a split second for digital signals to be recognized and properly decoded. Rapid repeated switching between inputs or settings can result in clicks or pops from the speakers as the unit attempts to lock on to the rapidly changing signals. · Make sure that fresh batteries are installed in the remote.
